RATE OF EXHAUST FLOW CALCULATIONS
Based on the 2004 International Mechanical Code (IMC).
The Rate of air flow required for a vent hood is now based on the linear length of the face of the hood
instead of the area of the hood opening. The length of the hood is measured along the front side that
is parallel with the front line of the appliance (LENGTH, Fig. 9).
For hood designs not covered by these calculations consult the latest edition of the IMC or other local
codes.
Type of Hood CFM per Linear Feet of Hood
Wall Mounted Canopy 200 CFM
Single Island Canopy 400 CFM
Subtract make-up air flow supplied directly to a hood cavity from the total exhaust flow rate of the hood,
if applicable.
